    Abstract: Techniques for steering overlay network traffic along specific paths through an underlay network. The techniques may include determining a path through an underlay network that is optimized for sending a packet from a first node of an overlay network to a second node of the overlay network. The techniques may also include determining a destination address for sending the packet along the path from the first node to the second node, the destination address including a micro segment identifier (uSID) corresponding with an underlay node that is disposed along the path through the underlay network and trailing bits representing a portion of an address that corresponds with the second node. The techniques may also include causing the packet to be modified to include the destination address such that the packet is sent from the first node to the second node along the path.

    Abstract: A method is provided in one example embodiment and includes receiving a request to create a path through a network, wherein the path originates on a first network device and terminates on the second network device; identifying a first controller associated with the first network device, wherein the first controller proxies control plane functions for the first network device; identifying a second controller associated with the second network device, wherein the second controller proxies control plane functions for the second network device; and computing the path using the first controller as a source and the second controller as a destination. The first controller installs the computed path on the first network device and the second controller installs the computed path on the second network device.

    Abstract: Techniques for informing a network of an application's service-level agreement (SLA) objective(s) so the network can ensure the SLA is met end-to-end, thereby allowing core network support of deterministic SLA and application-based routing without using network-based application recognition (NBAR) and/or compromising user privacy. The techniques may include receiving a first connection request to establish a network-domain connection between different network domains that meets or exceeds a service level objective. Based on the first connection request, the network-domain connection may be established between the different network domains to meet or exceed the service-level objective. In some examples, a second connection request may be received to establish a tunnel between a source application and a destination application, which are disposed in the different network domains. Based on the second connection request, the techniques may include establishing the tunnel between the source application and the destination application utilizing the network-domain connection.
